Will Power won at Sonoma Raceway for the third time in four years Sunday, earning his first victory of the IndyCar season when he took advantage of a late penalty to Scott Dixon for injuring three members of Power's pit crew.

Dixon led until he received a drive-through penalty with 15 laps to go for clipping a tire in the left hand of Power's tire holder while Dixon drove out of his pit directly behind Power's spot.

The tire holder went flying into another crew member, and a third member was injured by an air gun.
